I have a 98 A4 turbo. For a few weeks now my car has no power--No boost--My blow off valve is not making any noise at all. The other day I took a Hard right turn and all of a sudden POWER--for about 2 min. I put a new blowoff valve on thinking it was that...Still nothing.. I have to floor it to get my car going--Imagine how much gas im using. I heard that it might be a sensor on the turbo that the turbo is reading full boost? Can anyone Help

 

Take out your BOV and put in a DV. Then check for boost or vac leaks.

 

Now my BOV is inbetween the IC and the EM. Can I put the DV there?
